Error Resilient Image Communication Using Content-Based Multiple Description Coding**This work was supported by the Natural Sciences and Engineering Research Council of Canada and McMaster University.

Multiple description co ding has been studie d as an approach for transmission of images over error prone envir onments. The multiple description coding method propose d here takes into ac count the content of the image and provides the least amount of de gradation, cause d by loss of descriptors, for those arms of the image which are of greater inter est.
